Builds on #1618. Variables::get and Variables::collection take an exact id before a name; stored mode ids go through Collection::mode_by_id (expressions, the prototype's mode switch); font family variables and the colour picker, prototype editor and panels read stored ids exactly. Ported from fix/stored-ids-exact.
The engine notes when a drag has only moved the selected layers by one offset (Interaction::moved_by); the canvas keeps the outlines, box and slots from the drag's start document and shifts them, the selection spacing and the Design panel's values (but the position fields) come from that document, and the Export section's values are kept. Dragging 648 layers: UI pass 2.10 to 1.44 ms a frame.
* M12: create the next board shape already connected (#1597)
A selected sticky or shape shows a + beside each side; hovering one previews where the next goes, clicking makes one of the same kind, size and colour there, joined by a connector, and starts typing in it, in one undo step. board.addConnected {id?, side?, edit?} does it from commands.
* M12: the connected-shape handle and command in every full catalog (#1597)
* M12: Shift+Cmd/Ctrl+Enter on a board shape adds the next one already connected (#1597)
Fonts name a family by its typographic name and by a legacy name per weight; fonts without typographic names are installed under the legacy ones only. FontDb::resolve finds either from the other, and matches names across case, spaces, hyphens and underscores; every lookup (import, paste, REST import, rendering, missing fonts, the font report) uses it. A weight-number style goes by that weight, and .fig and REST imports wait for the installed fonts to be indexed.
A colour variable's value in a mode can now be {"alpha": {"variable", "opacity"}} - that
variable's colour with its alpha replaced - or {"mix": {"from", "to", "t"}}, a per-channel blend
of two colour variables or literals over the stored values (in the document's colour profile),
alpha included. Calculations resolve lazily like aliases, so bound layers, mode switches,
instances and undo follow their sources; they compose, and a loop, or a calculation that reads
more than 32 variables in its collection's modes (other collections in their default modes), is
refused when it is set. Operands are stored by id and read by exact id, as stored references
are. Files keep them; REST, CSS, Penpot and .fig exports write the colour they show in each mode;
deleting a source leaves its readers on the colour they showed; library import and swap
re-point their operands. The Variables panel shows them with their formula and can swap one for
an alias or detach it to its colour.
* M8: opening a file contacts no team library server it names until you check it (#1097)
* M8: translate the team library check strings (#1097)
* M8: the Assets panel library test checks what allows a library, without its own fake link (Sonar duplication and coverage)
* M8: cap the people a client keeps track of and the deleted ids a session remembers (#1121)
A hostile host or server could grow a client's presence, seen-peers and who-is-here lists without bound, and a session's deleted-id set only grew. Clients keep at most MAX_PEERS (4,096) others, leaving newcomers out with a warning; max_people is at most that; a session remembers at most 262,144 deleted ids, the lowest forgotten first.
* M8: a max_people above what clients track is lowered with a warning, not refused (#1121)
Refusing it would stop a server whose existing config says more from starting after an upgrade. Config::people() lowers max_people to MAX_PEERS for the core's limits, and the startup warnings name the configured and the used value.
* M8: the live welcome's handling in its own function (Sonar S3776)
A panic in a Session::grouped closure outside any command skipped the group rollback: the
documents stayed half edited, the history limit unbounded, live documents held and the group
depth raised. checkpointed now catches the unwind, runs the same rollback as a failed group and
resumes the panic, so the caller's guard still reports it.

Every pointer move draws about three frames, and the canvas hit-tested the hover on each: a hover where nothing changed since the last (place, modifiers, zoom, file, page, revision, selection, tool and modes) is no longer sent to the tools again. Dragging an auto layout frame laid its contents out again on every move: a frame whose only change is its transform now keeps its own layout (its parent's still runs). ui.inspect reports frameTimes. Measured on a synthetic 1,900-layer file: hover UI pass 0.91 to 0.49 ms a frame and CPU 33% to 22% of a core; normalise while dragging 648 layers 3.8 to 2.1 ms a move.
A double-click with the pen drew on: its second press added a point on the last one, and a double-click meant to edit a layer drew a stray vector on it. A press on the last anchor now adds nothing; a double-click ends the path (or, when it only started one, edits the layer under it) and Enter ends the path, both going on in vector edit mode with the Move tool. In edit mode the pen's Enter and double-click take the Move tool, the double-click taking back what its first press began. Escape still keeps the pen (#760).
* M6: FigJam .jam files open like .fig files (#1342)
A .jam is the same archive as a .fig (its canvas header reads fig-jam.), which the .fig reader already took; File > Open and its filter, drag and drop, file.import and the command line now take .jam too, and the home screen shows its thumbnail. FigJam layers come in as the .fig reader makes them (stickies and shapes with text as frames with their generated layers, other FigJam layers as frames or vectors with a note, unknown types left out with a note). Tests use a synthetic fig-jam. canvas and a .jam made from our own export.
* M12: a FigJam .jam file opens as a board (#1342)
The .fig reader marks a canvas with FigJam's fig-jam. header as FileKind::Board, so a .jam opens with the board toolbar, the dot grid and the board panels and saves as a board; a .fig stays a design file, and importing a .jam into an open file leaves its kind alone. Its objects stay ordinary layers (frames and vectors with the existing import notes). Builds on the .jam opening branch (#1586).
Someone who joins with a comment link (or its join code) sees the file live and adds, replies to, reacts to and resolves comment threads, but can't change the design: their app refuses other edits and the server accepts a comment link's batch only when every change in it touches comment threads. Sharing online makes a comment link and code beside the edit and view ones; the Share popover offers Can edit, Can comment and Can view, and the commenter's toolbar shows a Can comment badge with Move, Hand and Comment.
Backward compatible: clients announce the comments word; one that doesn't is welcomed with a comment link as a viewer and gets comment links listed as view links, a level this build doesn't know reads as view, and an older server that can't make a comment link leaves the share without one.
Each sweep takes at most 250 000 segments and 2 million possible crossings (pairs of segments whose bounds overlap, counted in O(n log n)), and a fold at most 4 million segments swept over its steps; past them the operation is refused with PathOpsError::TooComplex before it runs. A boolean group past the caps draws without its result, with a warning once, and the refusal is cached; vector.flatten refuses it instead of dropping it.
Properties were listed by name, so a rename moved one. Components now keep prop_order (the names as they were made; a rename keeps the place) and every listing follows it. Make slot opens a name field under the frame's Slot row; Enter makes the slot, Escape cancels, a taken name keeps the field open.
Session::execute_as records the agent's presence: its name, the file, and the innermost layers its last edit changed or the selection it set, for 8 seconds after its last command. The app shows it as an avatar in the people row and an outline with a name tag on the canvas, in its own colour. Display only: no undo step, never saved, never synced to a live session.
Every message (the first and each reply) gets `mentions`: {name, known,
you} for each @mention, by the rule the thread view highlights with
(figcraft_doc::mentions, now shared with mention_ranges). Names resolve
against the file's people and you; unknown names are kept with
known: false; a@b.com mentions nobody.
The board canvas's background grid is now a preference (`board.grid`): dots
(the default), lines, graph paper (a strong line every 2-12 cells over fainter
ones, like Japanese section paper) or none, with spacing (4-512), mark size and
contrast. Preferences gets a Board grid section; right-clicking an empty board
offers Board grid settings. Zoomed out the grid still thins out (by halves, or
down to graph paper's strong lines), and dots no longer shrink to a single
pixel, so the grid stays visible at low zoom.
The renderer draws lines as well as dots, with a configurable strong-mark
rhythm; a crossing of two lines is blended once, in the stronger colour. A
hand-edited preferences file falls back to the default grid instead of losing
the other preferences.

* M2: components can't contain their own instances (#1084)
Edits that would make a component hold an instance of itself, directly, through other components or through another variant of its set, are refused with the loop named. Files holding such a loop open with one instance per loop detached and a note; a rebuild never expands an instance inside a copy of itself, so a loop merged in a live session stops growing.
* M2: a variant may hold a sibling variant's instance; only true loops are refused (#1084)
Each variant counts as its own component: refusals and open-time repairs apply only to a component leading back to itself through instances (an instance-swap value included), so files with nested sibling variants open unchanged. sync_instance_depth is split into match_layers and copy_layers.
With map: true, edit.duplicate also returns map: each original layer's id, descendants included (nested frames, groups, instances and their sublayers), paired with its copy's id, so a batch can edit inside a copy through a step reference instead of inspecting it. Without map the result is unchanged.
Tools that act on a document, and the control methods engine.execute,
document.inspect, node.get and ui.render, take an optional `document`
(an open file's id from doc.list / document.inspect, or its path). The
call acts on that file and the tab in front stays in front, so an
attached agent keeps editing its own file when the user switches tabs.
Every command an MCP client runs acts as the client's name from initialize (clientInfo.title, else .name) with ' (agent)' after it, or 'AI agent' without one, carried to the app as engine.execute {agent}. Its messages, reactions and read state are its own, and its messages are marked (agent: true in the file and comment.list, an Agent label in the thread). The user's name and comments made in the app are unchanged; in live sessions the name and marker travel with the thread.
* M1: Crop image from the Object menu, the right-click menu and the image fill row (#1464)
* M1: crop mode shows the image dimmed outside the layer and heavier crop marks (#1464)
* M1: the handle overlay draws gradients and crops in their own helpers (#1464)
Dragging a guide, or moving one, now snaps to nearby layer edges and centres on the guide's own axis: within 5 screen pixels, gated by Snap to Objects and suspended with Cmd/Ctrl. Page guides see the page's top-level layers; frame guides see the frame's box, its layout grids and every visible layer inside it, in the frame's own space.
Snapping sits in the interaction path (canvas/guides.rs, not guide.add/guide.move) so the commands stay deterministic for the control channel and MCP. Tests: guide_snap_tests.rs in the engine and ui-egui crates; docs/ui-parity.md updated.
